Sochin is one of the Shotokan blackbelt kata. It is a powerfull kata with many double handed techniques. When used in competition it is generally chosen by bigger karateka, as it tends to suit that build of person more so than a lighter person.

I believe it also exists in Shito-Ryu, but I haven't seen it done so couldn't tell you how it compares.

I'd add that it's main purpose is to train in the use of sochin- (Also called fudo- ) dachi, in a similar way as Hangetsu Kata is meant to train in the use of hangetsu- dachi.
